Radiometric age validation of Atlantic tarpon, Megolops atlanticus.(Statistical Data Included)
July 1, 2001... Abstract--An improved radiometric aging technique was used to examine annulus-derived age estimates from otoliths of the Atlantic tarpon, Megalops atlanticus. Whole otoliths from juvenile fish and otolith cores, representing the first 2 years...

Effect of the salt-box catch-bycatch separation procedure, as used by the Texas shrimp industry, on short-term survival of bycatch.(Statistical Data Included)
July 1, 2001... Abstract--Experiments were conducted to determine the effect of the salt-box catch-bycatch separation procedure, as used by the Texas shrimp industry, on short-term survival of bycatch. Bioassays were conducted on five economically important...

Trace metals in four structures of fish and their use for estimates of stock structure.(Statistical Data Included)
July 1, 2001... Abstract--Trace elements in calcified tissues have been suggested as one of the most powerful means for stock discrimination yet developed. The structure of choice for determining elemental composition or fingerprints is the otolith,...

Estimating the number of fish in Atlantic bluefin tuna (Thunnus thynnus thynnus) schools using models derived from captive school observations.(Statistical Data Included)
July 1, 2001... Abstract--Aerial photographic assessment is a promising technique that could be structured to yield a fishery-independent index of abundance for Atlantic bluefin tuna, Thunnus thynnus thynnus (ABT). The accuracy of this approach may be...

Effects of gear selectivity and different calculation methods on estimating growth parameters of bluefish, Pomatomus saltatrix (Pisces: Pomatomidae), from southern Brazil.(Statistical Data Included)
July 1, 2001... Abstract--We examined the effects of gear selectivity and the consequences of a chosen method for estimating growth parameters of bluefish, Pomatomus saltatrix, from southern Brazil. Samples were obtained from commercial landings at Rio Grande...

Nursery habitats for ladyfish, Elops saurus, along salinity gradients in two Florida estuaries.(Statistical Data Included)
July 1, 2001... Many fish species use estuaries of the southeastern United States as nurseries (e.g. Skud and Wilson, 1960; Gunter, 1967), but coastal habitat degradation threatens many of the economically important fisheries that rely on estuaries (Gilmore,...

The validity of the fin-ray method of age determination for lingcod (Ophiodon elongatus).(Statistical Data Included)
July 1, 2001... Abstract--Oxytetracycline (OTC) injections were used in a mark-recapture experiment undertaken to validate the fin-ray method of age determination of lingcod (Ophiodon elongatus). In most cases, the number of annuli that formed beyond the OTC...

The behavior, growth, and survival of witch flounder (Glyptocephalus cynoglossus) larvae in relation to prey availability: adaptations to an extended larval period.(Statistical Data Included)
July 1, 2001... Abstract--Foraging behavior and prey abundance are significant factors determining the survival success of fish during the larval stage. Witch flounder (Glyptocephalus cynoglossus) are reported to have the longest pelagic stage of any northwest...

Lack of divergence between 16S mtDNA sequences of the swimming crabs Callinectes bocourti and C. maracaiboensis (Brachyura: Portunidae) from Venezuela(*).(Statistical Data Included)
July 1, 2001... Abstract--Lake Maracaibo, a large Venezuelan estuarine lagoon, is reportedly inhabited by three species of the genus Callinectes Stimpson, 1860 that are important to local fisheries: C. sapidus Rathbun, 1896, C. bocourti A. Milne Edwards, 1879,...

Feeding habits, prey fields, and potential competition of young-of-the-year walleye pollock (Theragra chalcogramma) and Pacific herring (Clupea pallasi) in Prince William Sound, Alaska, 1994-1995.(Statistical Data Included)
July 1, 2001... Abstract--Diets of young-of-the-year (YOY) walleye pollock (Theragra chalcogramma) and Pacific herring (Clupea pallasi) were compared between seasons (summer and autumn), years (autumn), and allopatric and sympatric fish aggregations (autumn)...

Age and growth of the bigeye tuna, Thunnus obesus, in the western Pacific Ocean.(Statistical Data Included)
July 1, 2001... Abstract--Bigeye tuna (Thunnus obesus) age and growth studies were last conducted in the western Pacific in 1967 and no study has ever attempted to age bigeye tuna from this area by using dorsal spines. The objective of our study was to...

Nocturnal occurrence of the swimming crab Ovalipes punctatus in the swash zone of a sandy beach in northeastern Japan.(Statistical Data Included)
July 1, 2001... Swimming crabs belonging to the genus Ovalipes (Crustacea: Brachyura: Portunidae) are distributed worldwide along sandy coastlines of subtropical and temperate waters (Stephenson and Rees, 1968). They are extremely well adapted to life on sand,...
